AB  - BACKGROUND AND PURPOSE: Branchial cleft cyst is a common congenital lesion of the neck. This study evaluated the efficacy and safety of ethanol ablation as an alternative treatment to surgery for branchial cleft cyst.MATERIALS AND METHODS: Between September 2006 and October 2016, ethanol ablation was performed in 22 patients who refused an operation for a second branchial cleft cyst. After the exclusion of 2 patients who were lost to follow-up, the data of 20 patients were retrospectively evaluated. All index masses were confirmed as benign before treatment. Sonography-guided aspiration of the cystic fluid was followed by injection of absolute ethanol (99%) into the lesion. The injected volume of ethanol was 50%–80% of the volume of fluid aspirated. Therapeutic outcome, including the volume reduction ratio, therapeutic success rate (volume reduction ratio of &amp;gt;50% and/or no palpable mass), and complications, was evaluated.RESULTS: The mean index volume of the cysts was 26.4 ± 15.7 mL (range, 3.8–49.9 mL). After ablation, the mean volume of the cysts decreased to 1.2 ± 1.1 mL (range, 0.0–3.5 mL). The mean volume reduction ratio at last follow-up was 93.9% ± 7.9% (range, 75.5%–100.0%; P &amp;lt; .001). Therapeutic success was achieved in all nodules (20/20, 100%), and the symptomatic (P &amp;lt; .001) and cosmetic (P &amp;lt; .001) scores had improved significantly by the last follow-up. In 1 patient, intracystic hemorrhage developed during the aspiration; however, no major complications occurred in any patient.CONCLUSIONS: Ethanol ablation is an effective and safe treatment for patients with branchial cleft cysts who refuse, or are ineligible for, an operation.BCCbranchial cleft cystEAethanol ablationUSultrasonography
